Oh no. I didn't say that. I said they *might* have been saved. With Rasputin so defacing the Imperial family, they were destined to disaster; without his input, they may have lived on.
I personally think that Nicholas II made a poor tsar, and he did not help himself. The Imperial family do not seem to have know *how* to help themselves, from what I can tell. Take the Duma, for example. That could have helped them, but Nicholas made it a failure.
I agree, Rasputin was not the only factor. However, I do think he was a major factor.
